James Egan Holmes appeared in Court on Monday for the preliminary hearing in the case of Aurora, Colorado Movie Theater shooting, in which Holmes is charged with several counts of murder and attempted murder.

During this hearing, Judge William Sylvester will decide whether prosecution has enough evidence against alleged shooter James Egan Holmes to head to trial.

Prosecution presented Jason Oviatt, of the Aurora Police Department as one of their witness. Officer Oviatt told the court that at the time of arrest, the 24-year-old was "very relaxed," as reported by NBC News.

Upon his arrest, Oviatt said, "He "didn't have normal emotional responses," as reported by NBC News.

Now it remains to be seen whether the former Ph.D. will make a plea at today's hearing or not. . It has been assumed that he will likely plead 'Not Guilty' on account of mental illness/incompetency.

A few months ago the prosecution under Chief Deputy District Attorney Karen Pearson added 14 additional charges to the 116 counts of attempted murder and 12 counts of murder.

Holmes is currently being held at the Arapahoe County Detention Center.

Most crucial documents in the Aurora shooting case have been kept sealed, very few documents have been released to the public, and those that have been exposed are heavily edited. However, the 911 calls and videos presented by prosecution in the hearing Monday will likely be released to the public and media alike.

On July 20, at a midnight screening of the cult-inducing Dark Knight Rises film at a movie house in Aurora, Colorado, Holmes, opened fire killing 12 people and injuring 59 others. He was arrested that morning and placed in custody.
